CULTIVATOR ATTACHMENT.

Specification of Letters Patent.

Patented May 2, 1911.

Application filed February 9, 1911. Serial No. 607,499.

To all whom it may concern:

Be it known that I, Donn D. MOMILLIN, a citizen of the United States,residing at Quenemo, in the county of Osage, State of Kansas, haveinvented certain new and useful Improvements in Cultivator Attachments;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to cultivators and has for its object to providea novel stalk cutter that may be readily secured to most of thecultivators commonly known as gang disk cultivators.

A further object of the invention is to provide a stalk cutter which maybe secured in position through the instrumentality of a pair of bolts,the stalk cutter hangers being so constructed as to form lock nuts whichwill prevent working loose of the bolts and consequent wabbling of thestalk cutter during operation.

lVith the above objects in view the invention resides specifically inthe novel form of stalk cutter hanger and more generally in the noveldetails of construction and com bination of parts hereinafter fullydescribed and claimed.

In the accompanying drawing forming part of this specification, Figure 1is a rear elevation of a cultivator with stalk cutters embodying myimprovements attached thereto. Fig. 2 is a longitudinal sectional viewtaken on the line 2-2 Fig. 1. Fig. 3 is an enlarged longitudinalsectional View through the stalk cutter. Fig. 1 is an end elevation ofthe stalk cutter shown in Fig. 3.

Referring now to the drawing in which like characters of referencedesignate similar parts, a cultivator 10 of the ordinary sulky type isshown, this cultivator having rearwardly extending gang beams 11, therear end of each beam terminating in a vertically disposed tubularbearing 12 the lower edge of which is formed with a substantiallycircular flange 13, and the bore of this bearing is tapered as shown at14 in order to snugly receive the tapered spindle of the stalk cutterhanger.

The stalk cutter hangers each comprise a tubular bearing head 15 fromone side of which extends a shank 16, the shank being provided centrallywith a longitudinal recess which lightens the shank and forms spacedparallel arms 17, these arms being terminally connected by a taperedhollow spindle 18 which is designed to snugly fit in the bore of thegang bearing, and is provided at its juncture with the arms withacircular stop flange 19 which is designed to abut the lower face of thegang bearing flange 13. A bolt 20 is engaged through the bore of thespindle, the head of the bolt 21 fitting between the spaced arms of thehanger, and being of such size as to be incapable of rotation betweenthe arms, the arms consequently serving as a lock nut. A washer 22encircles the bolt and bears against the top face of the gang beambearing, and a nut 23 is threaded on the bolt and advanced intofrictional contact with the washer, and serves to draw up the bolt untilthe upper and lower faces of the gang bearing are frictionally engagedby the flange 19 and washer 22 of the hanger, and independent rotationof the spindle within the bearing positively prevented until the nut isloosened.

A shaft 24 is revolubly mounted in the bearing head 15 of the hanger,and to one end of this shaft is keyed a curvilinear spoked wheel. 25.The spokes of the wheels of both hangers are connected by cutting blades26 which sever stalks near their roots during advancement of the stalkcutter over a stubble field.

It will be noted that the hangers of the stalk cutter are secured to thecultivator gang beam through the instrumentality of but two bolts whichare positively held against rotation during the operation of applyingthe stalk cutter to the beam and also during advancement of the stalkcutter over a stubble field, and thus the time and manual labornecessary for applying the device is reduced to a minimum and alsowabbling of the device while cutting stalks positively prevented.

What is claimed, is

A stalk cutter including a hanger having a tubular bearing head, a shankprojecting from said head having a longitudinal recess forming spacedoppositely disposed arms, a hollow spindle connecting the terminals ofsaid arms and having a stop flange in close proximity to said arms, abolt engaged through the bore of said spindle and having its headagainst said stop flange and between said arms, said arms preventingrotation of the, bolt head, a washer on said bolt, a nut on said boltengageable with the outer face of said washer and operatingrto move saidIn testimony whereof, I afiix my signawasher in the direction of saidstop flange ture, in presence of two witnesses.

\ T whereby the Washer and stop flange co-act DODE MQMHJLIB' in forminga clamp, a shaft engaged Witnesses: through said head and a stalkcutting Wheel L. L. MARIE, mounted on said shaft.
